Cancer in younger Adults is due to Accelerated Aging

By Ray Schilling | alcohol, Cancer, Cardiovascular disease, diet, Heart Disease, Mortality, Processed food, telomeres

Recent research showed that cancer in younger adults is due to accelerated aging. Researchers presented a paper at the American Association for Cancer Research (AACR) Annual Meeting 2024. They discussed in detail how cancer presents in aging tissues.

Details of the study

Researchers examined the UK Biobank databases of 148,724 individuals aged 37 to 54 years. 9 biomarkers from blood of these patients served to calculate the biological age of these patients. The following were the blood tests: albumin, alkaline phosphatase, creatine, C-reactive protein, glucose, mean corpuscular volume, red cell distribution width, white blood cell count, and lymphocyte proportion. I will discuss below how they calculated the biological age from these factors. In most patients there was a discrepancy between the chronological age and the biological age.

The researchers also checked the cancer registries to check how many cancer patients were found before age 55. Nearly 3200 cancers were found. Patients born between 1950 and 1954 were compared to patients born in or after 1965. Surprisingly the younger patients (born in or after 1965) had 17% higher accelerated aging. This made this group more prone to develop early cancers.

Significance of accelerated aging regarding cancer frequency

The researchers also found that increases in accelerated aging were associated with a significant risk of early-onset lung cancer, early-onset gastrointestinal cancer, and early-onset uterine cancer. Individuals who had the highest amount of faster aging were compared to people who had the smallest amount of faster aging. The faster aging group had twice the risk of early-onset lung cancer, more than 60% higher risk of gastrointestinal tumors, and more than 80% higher risk of uterine cancer.

Calculating the biological age

The following is a list of items to calculate the biological age (taken from this CNN source):

albumin: a protein made by the liver that declines with age
creatinine: a waste product in blood produced by protein digestion and the breakdown of muscle tissue; a measure of kidney function. Lower levels correlate with better longevity.
glucose: With age, blood sugar stays higher for longer after meals.
c-reactive protein: made by the liver in response to inflammation; relatively higher levels correspond to faster aging
lymphocyte percent: The concentration of these white blood cells related to immune function tends to decrease with age.

More items to calculate biological age:

mean cell volume: a measure of the average size of red blood cells, which increases with age
red cell distribution width: the difference between the size of a person’s smallest and largest red blood cells, which tends to increase with age
alkaline phosphatase: an enzyme produced mainly by the liver and bones that tends to increase with age
white blood cell counts: Numbers of white cells in the high end of the normal range in the blood may correspond with greater aging.

Using these criteria, a research group developed the algorithm PhenoAge. This is how the biological age was calculated.

What factors lower the biological age?

There are 8 essential components that determine your biological age: diet, physical activity, avoiding nicotine exposure, sleep health, lower body mass index (BMI), cholesterol, blood sugar, and blood pressure. This link states that when you optimize this list of 8 essential components your biological age will be 6 years less than your chronological age. It will make you resistant to several diseases including cancer.

Your telomere length is important to reduce your biological age

Researchers know for some time that telomere length determines the biological age. Telomere length determines how old we get. It also can predict whether we get illnesses like cancer and cardiovascular diseases as we age. In addition, it determines whether you get the blessing of longevity or not. Researchers showed that two lifestyle habits, namely a Mediterranean diet and regular exercise, preserve our telomeres to give us a younger biological age.

Effect of Junk foods on our biological age

Too many people eat unhealthy foods like processed meats, French fries, hamburgers and other processed foods. How does this affect your lifespan? When we consume unhealthy foods and beverages, like sugar-sweetened beverages and highly processed foods, we gain weight. Obesity and other chronic conditions are the results that put us at a higher risk regarding at least 13 types of cancer. Included in this are endometrial (uterine) cancer, breast cancer in postmenopausal women, and colorectal cancer.

How can we counter the devastating effect of highly processed foods?

We need to buy whole foods that were not processed. Buy fresh vegetables, fruit, nuts, organic chicken, fish like wild salmon. Cook your own meals. This link describes anti-aging foods that help you to enjoy a longer life with less diseases. Other studies showed in the past that this type of food preserves your telomeres, prevents many cancers and prevents heart attacks and strokes.

Discussion

The study in the beginning of this review showed a higher cancer frequency in younger patients. This is a new concerning trend. But the study failed to show the reason behind this. In my opinion it is the fact that younger people nowadays have poorer lifestyles than in the past. They consume junk foods and larger amounts of alcohol regularly. This behavior pattern causes shortening of telomeres, lowering of the biological age and the emergence of diseases mentioned above. We need more research into the causes of telomere shortening in younger patients. Also, why do they experience accelerated aging with an increase in the biological age? The research paper shown in the beginning of this review was done on a British population.

There is a need for other studies

A similar study with a more diverse population including a record of their eating habits would be welcome. Apart from measuring the biological age, measuring the telomere length would also be useful. In addition, a control group of younger people who consume healthy foods would help as a contrast. This control group likely would have a lower biological age and longer telomeres than the experimental group.

Cancer in younger Adults is due to Accelerated Aging

Conclusion

In the beginning of this review, I described a study about younger patients. They had an accelerated biological age with a higher rate of various cancers. I showed that other researchers examined telomere length and the longer it was the less cancer the patients got. I mentioned that eating junk foods, processed meats and consuming sugary drinks was bad for your health. This accelerates your biological age and shortens your telomeres. As this study was based on a British cohort, we need new research that concentrates on a more diversified population. Apart from measuring the biological age, measuring the telomere length would also be useful. In addition, a control group of younger people who consume healthy foods would help as a contrast. This control group likely would have a lower biological age and longer telomeres than the experimental group.

Any Form of Exercise is good

By Ray Schilling | Cancer, Cardiovascular disease, diet, exercise, Fitness, Health, heart attack, Mortality

Here are a few items that can prolong life; among them any form of exercise is good. This article concentrates on the exercise part in relation to longevity. A recent publication described how regular exercise prolongs your long-term survival. According to a study released on occasion of the American Heart Association’s Scientific Session 2023 there are 8 major factors that prolong life: healthy diet, physical activity, nicotine exposure, sleep health, BMI, cholesterol, blood sugar, and blood pressure. Among this group of factors regular physical activity plays a major role to prolong your life. Researcher who studied various people found that those who neglected their physical health had a chronological age of 53, but their average biological age was 57. On the other hand, a group of fit people who engaged in regular physical exercise had a chronological age of 41 years, but a biological age of 36.

Clinical trials showing that any form of exercise is good

JAMA Internal Medicine study by Dr. del Pozo Cruz

This study examined what the optimal amount of physical activity per week is to reduce mortality compared to an inactive population. 500,705 eligible US adults were observed for about 10 years. The abbreviations that the authors used in the study were as follows:

MPA: moderate aerobic physical activity

VPA: vigorous aerobic physical activity

MSA: muscle-strengthening activity

Results of mortality reduction with various amounts of physical activity

The best group engaged in more than 0 to 75 minutes of MPA combined with more than 150 minutes of VPA and 2 or more MSA sessions per week. Their mortality rate was 50% lower than an inactive comparison group.
The optimal combination for reduction of cardiovascular disease (CVD) and cancer mortality risk was as follows: more than 150 to 225 minutes of MPA, more than 0 to 75 minutes of VPA, and 2 or more MSA sessions per week. This reduced combined mortality of CVD and cancer by 70%.
The researchers stated that the adjusted mortality rates represented 50% lower mortality rate for all-cause and cancer mortality. The mortality rate for CVD mortality was 3-fold lower than for inactive controls.

Smallest amount of exercise that reduces mortality

In a study published in the European Heart Journal the authors asked how little exercise per week was enough to reduce mortality from heart disease. They found that it takes at least 15–20 min/week of vigorous physical activity (VPA) to reduce mortality from heart attacks by 16–40%. If you increased the exercise level by 50–57 min/week the mortality rates reduced even further.

Are physically active jobs healthy?

Recent research showed that people who work in physically demanding jobs are more likely to develop early cognitive impairment. This is the pre-stage of Alzheimer’s disease. 15.5 % of people who worked in high levels of occupational physical activity developed dementia. This compared to 9% risk for people whose work involved a low level of physical activity, not too much and not too little. The finding confirms the notion that there is a need for balance of physical exercise. Several publications stressed what is optimal in terms of exercise: vigorous (75 to 300 minutes per week) and moderate physical activity (150 to 600 minutes per week). People who expose themselves to these amounts of exercise live the longest and stay healthy.

Discussion

The studies discussed here showed that the right amount of exercise can reduce mortality from heart disease and cancer. However, exercise is not the only factor that can do this. It is important to combine regular exercise with a healthy diet. Your diet should consist of fruits and vegetables, whole grains, low-fat dairy products, lean proteins and limit saturated and trans-fat, added sugars, and sodium. In addition, you need enough sleep, maintain a healthy weight, manage your stress, and don’t smoke.

Any Form of Exercise is good

Conclusion

In this review I touched on the importance of regular exercise to reduce mortality from heart disease and cancer. Vigorous (75 to 300 minutes per week) and moderate physical activity (150 to 600 minutes per week) reduce mortality from heart attacks by 16% to 40%. But physical exercise is only one factor of mortality reduction. If you want the full benefit from other factors, you must quit smoking, eat a Mediterranean type diet with fruits and vegetables, whole grains, low-fat dairy products and lean proteins. Also you should limit saturated and trans-fat, added sugars, and sodium. In addition, you need enough sleep, maintain a healthy weight and manage your stress. Once you adopted this lifestyle, you live longer and you will get less diseases.

News from the Blue Zones Regarding Longevity

By Ray Schilling | alcohol, andropause, Cancer, Cardiovascular disease, diet, exercise, heart attack, Hormones, lifestyle, Menopause, testosterone

This article is about news from the Blue Zones regarding longevity. Blue Zones are areas where many centenarians live. Medical News Today ran a review article about Blue Zones on Sept. 23, 2023. These Blue Zones are located in Sardinia, Italy; Ikaria, Greece; Nicoya, Costa Rica; Loma Linda, California and Okinawa, Japan. Many studies looked at centenarians in these areas and analyzed what lifestyles led to their longevity. Dan Buettner summarized at a conference that only 20% of deaths in the world are due to genetic conditions. 80% of people can postpone their death date by adopting healthy lifestyles.

Factors associated with longevity

Dan Buettner called the factors that lead to prolonged life “Power 9”. The following factors must be adopted simultaneously, if you want to reach 100 years of age and more:

Moving naturally and regularly
People in Blue Zones have a purpose in life
Reduce stress in your life
Practice the 80% diet rule, which is to stop eating when 80% full
Adopt a plant-based diet.
Consume alcohol in moderation
Be part of a community
Put family first
keep a social circle that supports healthy behaviors

A diet for longevity

Dan Buettner analyzed the dietary habits of centenarians. He found that 90% of the diet they consumed consisted of whole food, plant-based sources and about 65% of their diet were complex carbs. Buettner noted: “The pillars of every longevity diet in the world are whole grains, nuts, greens, and other garden vegetables, tubers and beans.” For years the benefits of a Mediterranean diet were investigated and found to be life prolonging. It also emphasizes vegetables, whole foods, greens, grains, nuts and beans. The review article in Medical News Today that I mentioned above contains recommendations of how to change your diet to a healthier one.

Regular exercise

We are built in a way that requires regular exercise. When you exercise regularly, your body produces healthy HDL cholesterol that balances the unhealthy LDL cholesterol. Overall, this counteracts clogging of arteries and prevents heart attacks and strokes.

When you prevent strokes and heart attacks, you live longer.

Have a purpose in life

When you have a purpose in life, your mind is focused on what excites you. Achieving what is your dream satisfies you. Your brain releases feel-good brain hormones (dopamine, serotonin, endorphins, and oxytocin). When these hormones are released, you relax and cope with stress better. Your blood pressure normalizes, hardening of the arteries is postponed. At the same time, you prevent heart attacks and strokes. This contributes to longevity.

Reduce stress in your life

When under stress, your adrenal glands release adrenaline and cortisol. In the short term these stress hormones help you to cope better with stress. But when stress gets chronic, it weakens your immune system and increases your risk for a heart attack or stroke. It ages you faster. You can counter stress in your life by adopting stress management techniques. Regular exercise stabilizes your emotional life. You can listen to relaxation recordings or to relaxing music to calm your nerves. Developing friendships is another method of coping with stress. Here is more information on how to reduce stress in your life.

Limit alcohol consumption

In the past it was thought that small amounts of alcohol would prevent cardiovascular disease. But these studies overlooked the fact that even small amounts of alcohol can cause various cancers. So, by limiting the amount of alcohol consumption you also limit your probability of getting cancer.

Be part of a community

Many psychological studies showed that social isolation leads to health problems. It follows from this that being part of a community stabilizes your health and prevents disease. When you socialize with other people you counter stress and prevent loneliness.

Putting family first

When you care about your family, family members will care about you. Studies showed that this is an important factor in preventing disease. It even reduces mortality. Lower mortality leads to longevity.

Keep a social circle that supports healthy behaviors

Strangely enough here is another psychological factor that leads to longevity: getting support from a social circle. Being part of a social circle can create positive energy that prevents health problems.

Discussion of factors that lead to longevity

It is interesting to see that a lot of the longevity factors are psychological in nature. But physical factors are also important, like a Mediterranean diet and regular exercise. One factor that was not mentioned by Dan Buettner is the importance of preservation of hormone stability. I attended many yearly conferences of the American Academy of Anti-Aging Medicine (also known as A4M). They take place in the middle of December in Las Vegas every year. Over the years many lectures centered around hormone deficiencies. They collectively lead to premature aging and deaths. However, speakers also stressed that when you replace the missing hormones, you can reach a balance point where life gets prolonged.

Hormone replacement

One of the speakers, Dr. Hertoghe, an endocrinologist from Brussels mentioned in various talks that a lack of human growth hormone (HGH) in older age can lead to premature death. When IGF-1 levels in the blood are low, replacing the missing HGH with regular HGH injections can add 26.5 years to your life expectancy. But other hormones like thyroid hormones, testosterone in males, and progesterone and estrogen in females can prolong life when replaced after menopause or andropause (the male version of menopause).

News from the Blue Zones Regarding Longevity

Conclusion

Many factors contribute to longevity in centenarians. A lot of the factors are psychological in nature, like having a purpose in life or reducing stress in your life. Others are: be part of a community, put family first and keep a social circle that supports healthy behaviors. Physical factors causing longevity are moving naturally and regularly; adopt a plant-based diet; and consume alcohol in moderation. There is one important factor of longevity that Dan Buettner overlooked: your hormone balance. When we approach age 60 and beyond many people stop producing adequate amounts of hormones.

Replacing missing hormones

Anti-aging doctors have done studies showing that replacing missing hormones in proper doses will prolong life. Dr. Hertoghe, an endocrinologist from Brussels mentioned in various talks that a lack of human growth hormone (HGH) in older age can lead to premature death. When IGF-1 levels in the blood are low, replacing the missing HGH with regular injections can add 26.5 years to your life expectancy.

Learn about Longevity from the Blue Zones

By Ray Schilling | diet, Fitness, Health, lifestyle, Mortality, Nutrition, Processed food, red meat, sleep

People who live in blue zones often turn 100 or older, so we can learn about longevity from the blue zones. The 5 most often cited blue zones are in Okinawa, Japan; Sardinia, Italy; Nicoya, Costa Rica; Icaria, Greece; and Loma Linda, California, United States. But there are many more blue zones throughout the world. These zones contain the most centenarians, people who have reached the age of 100. It is thought that it is the people’s lifestyle that makes them live much longer than the rest of the world.

Lifestyle of centenarians

People are active, are bicycling, walking, swimming, constantly on the go and they are careful about what they eat. They stay slim, but are muscular. Their diet consists mostly of vegetables and salads, with very little meat. They may consume a small piece of beef on Sundays, but not during the rest of the week. Fish may be a part of their diet two or three times per week.

Diet characteristic of blue zones

Sandee LaMotte published an article on March 4, 2023 at CNN, which describes the diet consumed in blue zones. People in blue zones are active, handle stress well, are close to friends, have a purpose in life and are often members of a social or religious group. They eat mostly a plant-based diet and they stop eating before they are full.

The food consists of complex carbohydrates. No processed foods are eaten. The American Heart Association says: “Complex carbohydrates, such as beans, peas, vegetables and whole grains provide vitamins, minerals and fiber that can go missing in processed and refined foods. In addition, they are digested more slowly, and the fiber helps you feel full longer.”

Origin of blue zone foods

The blue zone food has its roots in the African, Asian, Latino and Native American diets. Dan Buettner originally published an article about the blue zones in the National Geographic Magazine. Recently he published a collection of 100 blue zone recipes in book form.

The Mediterranean diet is very close to blue zone eating.

What blue zone meals contain

Buettner said: “The five pillars of every longevity diet, including the blue zone, are whole grains, vegetables in season, tubers, nuts and beans. In fact, I argue the cornerstone of a longevity diet is beans.” People in blue zones eat similar foods as those who eat a Mediterranean diet, but they do not eat as much fish as people on a Mediterranean diet. People on a blue zone diet don’t eat any milk products. On the other hand, goat and sheep’s milk cheeses such as feta and pecorino are part of the blue zone diet. In the blue zones the consumption of purple sweet potatoes, sesame seeds, fresh vegetables and fruit are the major staples.

More info about Blue Zone diet

All of the meals contain complex carbohydrates, micronutrients and a whole variety of fiber.

Perhaps the important difference to the Standard American diet is that in the blue zone there is a lack of beef, hamburgers, processed foods and highly processed carbohydrates like bread, pasta, sugar-sweetened beverages, salty snacks like potato chips, candies, cookies and processed meats (bacon, sausages or cold-cuts). People in blue zones eat very little bread and if they do, they eat sourdough bread, which does not raise the blood sugar level as the highly refined white bread.

Recapturing healthy foods

So, what foods are blue zone people really eating? Tofu, quinoa, mushrooms, lentils, beans, turnip greens, artichokes, asparagus, chickpeas and spinach are the main staples of their nutrition. They stay away from sugar, rarely eat meat (once or twice per week) and otherwise have a healthy lifestyle. Scientists think that longevity comes from the healthy lifestyle and diet, which centenarians practice. Several longevity genes get activated as explained in this publication. This translates into living long lives with very few illnesses and experiencing energy until the end of their lives.

Learn about Longevity from the Blue Zones

Conclusion

We can learn a lot from observing what centenarians eat and do. Scientist have investigated the lifestyle of people living in blue zones in various parts of the world. These zones contain the most centenarians, people who have reached the age of 100. People in blue zones eat mostly vegetables and very little red meat. They avoid sugar and processed foods. But they are also very active, have a rich social life and allow themselves enough sleep. Scientists accumulated evidence that genetic longevity switches are activated by the life style of people living in blue zones. It is the activation of these epigenetic switches that are responsible for the longevity of people in blue zones.

Melatonin Is More Than a Sleeping Aid

By Ray Schilling | Alzheimer’s disease, Anti-aging medicine, Autism, autoimmune disease, Cancer, Cardiovascular disease, Circadian rhythm, Dementia, Diabetes, Health, heart attack, Heart Disease, Hormones, immune system, Inflammation, Insomnia, melatonin, Menopause, mitochondria, Multiple sclerosis, neurological disease, Osteoporosis, Parkinson’s disease, sleep, Stroke

Notably, the January 2021 issue of the Life Extension magazine informs you that melatonin is more than a sleeping aid. It contains an interview between Dr. Roman Rozencwaig and a Life Extension (LE) magazine reporter. It must be remembered that Dr. Rozencwaig dedicated much of his career to the healing effects of melatonin. Another keypoint is that in 1987 Dr. Rozencwaig published a paper together with two other researchers. Specifically, it showed that melatonin production by the pineal gland declines in older age. Markedly, they stated that this is the reason why people age and why diseases of aging develop. Another key point is that Dr. Rozencwaig also stated that taking oral melatonin can promote a healthier life.

Melatonin deficiency causing aging and various illnesses

With the aging process the pineal gland calcifies and melatonin production is steadily declining. Surely, along with this is a deterioration of the circadian hormone rhythm. Meanwhile, the neuroendocrine system in the brain gets disorganized. Accordingly, this causes various diseases to occur. To emphasize, Dr. Rozencwaig says that a proper balance between melatonin and neurotransmitters is what we need to maintain health and longevity. As a result, a daily intake of melatonin supports healthy aging and longevity.

The many clinical effects of melatonin

Oral melatonin tablets help you to fall asleep easier, particularly the population that is older than 60 years.

But besides that, melatonin has many other clinical effects.

Melatonin improves immunity, which improves resistance against infections. It helps also in cancer prevention
Melatonin maintains the circadian hormone rhythm by synchronizing pituitary and hypothalamic hormone production
It protects the brain and may prevent Parkinson’s disease, Alzheimer’s disease, multiple sclerosis, autism, and others
Melatonin modulates anti-inflammatory cytokinins in different diseases

Dr. Rozencwaig mentioned that melatonin slows down the aging process. There are multiple intertwining reasons for this.

Melatonin’s actions against the aging process

Melatonin regulates gene expression. This means that some signs and symptoms of aging can be reversed through genetic switches
Because melatonin regulates the immune response, the body is more protected against viral, bacterial and parasitic infections
Melatonin helps to overcome chronic inflammation that produces cytokines
Melatonin is also liver-protective through stimulation of an enzyme (AMPK). This enzyme regulates cellular metabolism.
There are other processes that melatonin is involved in: energy metabolism by protection and restoration of mitochondria.
Melatonin protects against osteoporosis by balancing and regulating bone formation versus bone loss.

More actions of melatonin

An important function of melatonin is the stimulation of antioxidant enzymes like glutathione peroxidase and superoxide dismutase (SOD)
Melatonin regulates sirtuins, which are proteins that maintain cellular health. They protect you from obesity, type 2 diabetes, cancer, heart attacks and strokes, dementia and more
As already mentioned, melatonin is a neuroprotective agent and may prevent Alzheimer’s and dementia
Melatonin stimulates apoptosis of cancer cells.
Oral health and melatonin are related. Melatonin suppresses herpes infections and periodontal disease. Melatonin prevents oral cancers to a certain degree. In addition, dental implants survive better when melatonin is present in saliva.

Prevention of cognitive decline

Dr. Rozencwaig mentioned that melatonin stops much of the cognitive decline of aging. To achieve this the following processes take place.

Melatonin improves the sleeping pattern and increases the amount of REM sleep.
During sleep melatonin removes toxic amyloid and tau proteins. We know that with Alzheimer’s disease these are the proteins that accumulate in the brain.
Melatonin improves myelination of white matter in the brain. This prevents brain atrophy of old age.
The brain is metabolically very active and produces toxic free radicals. But melatonin is a strong antioxidant dealing with free radicals. Melatonin can cross the blood brain barrier and stimulates enzyme production to eliminate toxic reactive oxygen species.
Chronic inflammation also increases with age, but melatonin deals with this condition in the brain.
Here are 3 subtypes of melatonin receptors. The body integrates the multitude of actions of melatonin with the help of these receptors.

Melatonin Is More Than a Sleeping Aid

Conclusion

Melatonin is a powerful antioxidant that has many other useful protective qualities as explained. The body integrates various functions like anti-aging, anti-free radical activity, neuroprotection in the brain and more. Melatonin even synchronizes pituitary and hypothalamic hormone production. This helps to integrate the effect of melatonin, which benefits the body in many ways. Melatonin prevents Parkinson’s and Alzheimer’s disease, multiple sclerosis, autism, obesity, type 2 diabetes, cancer, heart attacks, strokes and dementia. Melatonin production deteriorates from the age of about 60 onwards. It is important to supplement with melatonin at nighttime from that age on. Usually, you only need small amounts of melatonin, between 1mg and 3 mg at bedtime. This prevents most of the serious diseases of old age, stimulates your immune system and lets you age gracefully.

Ketogenic Diet With Ketone Supplementation

By Ray Schilling | Alzheimer’s disease, Anti-aging medicine, diet, Nutrition, Weight loss

There is a newer way to shed some pounds using a ketogenic diet with ketone supplementation. Ketosis with a ketogenic diet is difficult to achieve because it requires a lot of fat consumption and at the same time extremely low carb intake to trigger the ketogenic response. The October 2019 issue of LifeExtension magazine contained an article about a ketogenic diet with ketone supplementation. There are dip sticks with which you can test your urine for ketone bodies to verify that your metabolism has switched to ketosis. But you can also take some ketone supplements including beta-hydroxybutyrate. By adding this supplement it is easier to achieve ketosis.

Why do people think of starting a ketogenic diet?

Calorie restriction can mimic the effects of fasting. It leads to ketone production and improved energy metabolism. Your blood sugar goes down, you lose weight and diabetes becomes easier to manage. In an animal experiment with worms with the pretty name “C. elegans” researchers fed beta-hydroxybutyrate to these roundworms. They extended their lifespan by 20%.

Many who are motivated to go on a ketogenic diet hope to lose weight and others may hope to live longer. One large US study from the Brigham and Women’s Hospital, Boston, MA showed that mortality over a period of 25 years was lowest when carbohydrates were in the 50 to 55% range. In the same study when carbohydrates were replaced in ketogenic diets with animal-derived protein and fat sources, mortality increased by 18%. Meat and fat were from sources such as lamb, beef, pork, and chicken.

Problems with ketogenic diets

Physicians have had the concern that their patients on ketogenic diets tend to eat cheap fats and meats that contain trans fats. These unhealthy fats lead to premature death from accelerated hardening of the arteries resulting in heart attacks and strokes.

The alternative: a ketogenic diet with ketone supplementation

A new approach to anti-aging is taking ketone bodies like beta-hydroxybutyrate as a supplement. A publication from 2017 stated that oral ketone bodies could mimic the life extending properties of caloric restriction. The authors stated: “An exogenous ketone ester provides a new tool for mimicking the effects of caloric restriction that can be used in future research. The ability to power mitochondria in aged individuals that have limited ability to oxidize glucose metabolites due to pyruvate dehydrogenase inhibition suggests new lines of research for preventative measures and treatments for aging and aging-related disorders.”

Another publication from 2017 describes how ketones can be used as alternatives to glucose for energy. Brain cells and muscle cells in particular are very capable to utilize ketone bodies for energy. Two principal ketones are significant: acetoacetate and beta-hydroxybutyrate. The liver is involved when fatty acids are broken down and ketones are manufactured.

Ketone metabolism

Ketones provide energy without raising blood sugar levels or stimulating insulin secretion. The body requires less processing of ketones to release energy. This means that less NAD+ is used to metabolize ketones. The end result is that more NAD+ circulates in the body, which is used to repair damaged DNA and helps slow down the aging process. Ketones mimic many of the effects of caloric restriction and intermittent fasting dieting. Ketone metabolism reduces risk factors for diabetes and heart disease.

Human experiments

A 2018 study took 20 individuals aged between 18 and 35 years and tested them with an oral glucose tolerance test. Half of the subjects received a ketogenic hydroxybutyrate monoester, the other half just water (placebo group). The ketogenic group had 16% lower blood glucose levels. Their insulin sensitivity was 11% lower. The authors concluded: “These results suggest that ketone monoester supplements could have therapeutic potential in the management and prevention of metabolic diseases.”

Longevity in humans

There has been a lot of research in the last few years indicating that sirtuins (SIR1 and SIR3) are important anti-aging genes. NAD+ needs to activate sirtuins first to make them effective. Unfortunately with the aging process less NAD+ is available, which leaves the sirtuins genes inactivated.

In rat experiments feeding of a ketogenic diet resulted in increased levels of NAD+. The researchers measured an oxidative DNA damage marker in the hippocampus of the brain. This showed much less DNA damage in rats fed a ketogenic diet when compared to controls on a regular diet.

Study of humans with Alzheimer’s disease

Another human study examined the blood of Alzheimer patients, patients with mild cognitive impairment and normal controls. Alzheimer patients had low ketone levels in the blood as well as low 2-hydroxybutyric acid. Overall this showed that there is a change in metabolism in Alzheimer’s patients that leads to low ketone bodies in the blood on one hand and beta amyloid deposits on the other hand leading to memory loss.

A further experiment with Alzheimer’s patients showed that cognitive function improved after elevation of ketone blood levels following ingestion of beta-hydroxybutyrate.

A healthy way to raise ketones

Investigators in this human study determined whether various ketone-drinks were elevating blood ketone bodies reliably. 15 volunteers received ketone esters or ketone salts as a drink. There was a reduction of blood pH by 0.1 units using ketone esters. The ketone salts elevated the urinary pH from 5.7 to 8.5. An experiment with 16 volunteers measured the effect of having a meal before taking ketone esters. The ketone blood level showed a reduction of 33% after the volunteers consumed a meal and they took the ketone supplement afterwards. Ketone supplements lowered blood glucose, lowered free fatty acid and also lowered triglyceride concentrations. On the other hand, there was no change of the electrolyte levels. The authors said: “We conclude that exogenous ketone drinks are a practical, efficacious way to achieve ketosis.”

Ketogenic Diet With Ketone Supplementation

Conclusion

The liver produces ketones when a person is fasting or is on a ketogenic diet. However the high fat content of a ketogenic diet can lead to atherosclerotic plaques in the arteries with the subsequent developments of strokes and heart attacks. A much safer way of raising ketone bodies in the blood is by taking ketogenic supplements by mouth. Animal experiments and clinical trials have shown that oral ingestion of ketogenic substances appear in the blood stream within 30 minutes and remain there for 3 to 4 hours. The body tolerates ketogenic supplements well with no side effects.

Prevention of Alzheimer’s disease, achieving weight loss and longevity

They likely will play a larger role in the prevention of Alzheimer’s disease in the future. Ketogenic supplements may be an adjunct to weight loss diets. In addition, fatty acids metabolize into ketones, which turn into energy in brain cells and muscles. Oral ketones stimulate the formation of NAD+, which activate longevity genes (sirtuins). Older people have a hard time to metabolize glucose because of certain enzyme deficiencies. But the brain and the muscle tissue can metabolize ketones rapidly, even in older age. Unfortunately the price of such supplementation is forbidding at the present time.

What Makes Us Sick And What Keeps Us Healthy

By Ray Schilling | diet, food, green tea, lifestyle, Nutrition

An article in Nature Communication essentially asks what makes us sick and what keeps us healthy? The publication is about eating enough flavonoids to protect you from heart attacks and cancer.

The publication appeared on Aug. 13, 2019. It is a prospective study involving 56,048 participants of the Danish Diet, Cancer, and Health cohort. The medium age of the participant in the beginning of the study was 56 (range 52 to 60). This was cross-linked with Danish nationwide registries. The observation time was 23 years during which 14,083 participants died. As this study had a high number of participants and had a long observation period, the data are quite robust.

The researchers found that when people consume 500 mg of flavonoids from vegetables and fruit per day, they are dying significantly less from heart attacks and cancers.

Details of the study on flavonoid intake

Flavonoids are polyphenolic compounds in plant-derived foods and beverages such as vegetables, fruit, dark chocolate, coffee, tea, and red wine. There are six major subcategories of flavonoids: flavonols, flavan-3-ols, flavanones, flavones, isoflavones and anthocyanins. But it does not matter, which ones we consume, just that we consume enough (more than 500 mg per day).

The results were obtained with much stratification. For instance, in one set of results they normalized for age and sex. They called this model1. In another set they adjusted for age, sex, BMI, smoking status, physical activity, alcohol intake, hypertension, hypercholesterolemia, social economic status (income), diabetes, and prevalent disease. They called this model 2.

Participants with 536 mg of daily flavonoid intake had a reduction of 39% of heart attacks according to model 1. Using model 2 this changed to a reduction of 18% of heart attacks.

Cancer mortality reduction

The investigators did a similar analysis for cancer mortality reductions. At 536 mg of daily flavonoid intake model 1 showed a 36% reduction of cancer mortality. Model 2 still calculated a 21% reduction of cancer mortality. In both cases, the cardiovascular mortality risk and the cancer risk showed that more than 500 mg of flavonoids per day were not necessary as no more lives were saved by increasing the flavonoid dose beyond that. Unfortunately the opposite is true: people eat too many processed foods devoid of flavonoids, and they die of heart attacks and cancer prematurely.

Reducing the risk of heart attacks and cancer is not new

Many studies have shown what researchers found in this study, namely that vegetables and fruit can prevent heart attacks and cancer. Here is a brief summary with links to show this.

We heard many times that small amounts of alcohol consumption will keep the arteries clear of fatty deposits. This prevents heart attacks and strokes, but as the following study shows even small amounts of alcohol can cause various cancers.

Small doses of alcohol are still cancer producing

Dr. Timothy S. Naimi from Boston University Medical Center was the main investigator of an international team of scientists. The study found that every year 18,200 to 21,300 cancer deaths in the US (that is 3.2% to 3.7% of all US cancer deaths) are due to alcohol consumption. The authors of the study determined that every person who dies from alcohol related causes lost on average approximately 18 years of his/her life (scientists call this “years of potential life lost”). 51% of women developed breast cancer from alcohol exposure, 62% of men came down with upper airway and esophageal cancers. Less than 1.5 drinks per day caused between 26% and 35% of alcohol-related cancer deaths. There was no safe lower margin. The authors concluded, “Reducing alcohol consumption is an important and underemphasized cancer prevention strategy”.

Lifestyle important for longer life expectancy

I am reminded of a talk that Dr. David Katz delivered in a keynote address. He said that lifestyle improvements create profound changes in our system. This talk took place at the 22^nd Annual World Congress on Anti-Aging Medicine in Las Vegas Dec. 10-14, 2014. One study that was mentioned showed that in men who adopted a healthy lifestyle 35% of heart attacks could be prevented. With healthy lifestyle the authors meant consuming a healthy diet, not exceeding moderate alcohol consumption, no smoking, regular physical activity and having a normal waist circumference (less than 95 cm).

The ingredients you need to make it to age 100

A Swedish longevity study that went on for 50 years gave me the idea to write a blog about the factors that can help you to turn 100 and still have your mental capacity and good health.Let me introduce you to this study. Researchers at the Sahlgrenska Academy in Göteborg, Sweden (which is located at the University of Gothenburg) decided back in 1963 to follow a group of 855 Gothenburg men born in 1913 until they would either die or turn 100. The idea was to find out what killer diseases are in the way to reach such a ripe old age and if they would survive, what was it that made them reach this age. Think of it as a race to turn 100.

What diseases killed at older age and what led to longevity?

The researchers had checkpoints along that journey: various surveys were conducted at the age of 54, 60, 65, 75, 80 and 100 to analyze the factors that lead to longevity. 27% (232) of the original group reached the age of 80, and 13% (111) made it to 90. Only 1.1% of the men made it to the age of 100. What were the causes of death for the other ones who did not make it? 42% of deaths after the age of 80 were due to heart attacks, 20% due to infectious diseases, 8% due to strokes, 8% due to cancer, 6% due to pneumonia and 16% due to other causes. 23% of the men over 80 were diagnosed with Alzheimer’s or dementia. Factors that made people survive were refraining from smoking, maintaining a healthy cholesterol level and limiting coffee consumption to not more than 4 cups per day.

Beneficial effects of green tea and black tea

A meta-analysis involving 194,965 people and 4378 strokes found that there was a reduction of strokes with increasing tea consumption. Those who drank 3 or 4 cups of green tea or black tea per day were the experimental group. Researchers compared them to the control group that drank less than one cup of tea per day. The experimental group had a 21% lower risk of getting a stroke than the control group.

A meta-analysis of 18 studies from China showed that green tea and black tea consumption was beneficial for prevention of cardiovascular disease and for cancer prevention. The highest consumption of green tea reduced cardiovascular mortality (heart attacks and strokes) by 33%. The highest black tea consumption lowered mortality by 12%. Cancer mortality turned out different. Green tea did not produce a reduction in mortality, but black tea lowered it by 21%. I suspect that the different subcomponents of the bioflavonoid content in green and black tea are key to those findings.

Plant-based diet versus animal protein based diet

A 2016 study that had gone on for 49 years was involving 131,342 participants. Animal protein intake showed an association with higher mortality from heart attacks and strokes. The investigators substituted 3% of energy from processed red meat by an equivalent amount of plant protein. This reduced the all-cause mortality by 34%. For unprocessed red meat the 3% substitution reduced the all-cause mortality by 12%. If 3% of egg consumption is reduced, all cause mortality drops by 19%.

British Medical Journal study

A new study has shown that you can save lives when you replace red meat and processed red meat. The replacement was with fish, poultry or protein from vegetables. The study appeared in the British Medical Journal on June 12, 2019. It involved 53,553 women nurses and 27,916 male doctors in the United States and ran from 1986 to 2010. Here is my summary of the blog where I reviewed this study in detail. A new study in the British Medical Journal showed that an increase in red meat consumption of only ½ serving per day for 8 years caused an increased mortality of 9% over the following 8 years. With regard to processed red meat the mortality was even bigger, namely 13%. The researchers replaced some of the meat with white chicken meat or vegetables and the mortality normalized.

In contrast, a Japanese study showed that there was no increase in cardiovascular disease with the consumption of up to 100 grams of beef or other meat products per week. The study went on for 16 years.

Using antibiotics as growth promoters is illegal in Japan and Europe

I pointed out before that there is literature explaining why there is a discrepancy: the beef industry in the US feeds the animals antibiotics as growth promoters. This changes the bowel flora in humans who eat the beef. The changed bacterial strains in the gut use carnitine from beef and make trimethylamine N-oxide (TMAO). This is a toxin that causes both cardiovascular disease and cancer. This explains why in the US beef is one of the culprits that cause heart attacks and colorectal cancer. In Japan this is not the case. Both Japan and Europe do not use antibiotics as growth promoters in the cattle industry, as it is illegal.

In the US it is likely safe to eat organic meats (beef, chicken) as these meats will not contain antibiotics. Due to the numerous additives in processed red meat, it is a sensible idea to skip these products altogether, as they produce cancer.

What Makes Us Sick And What Keeps Us Healthy

Conclusion

Several studies have pointed out the importance of eating less animal protein and increasing vegetables and fruit in your diet. Heart attacks, strokes and cancers are still the major causes of death in all of the developed countries. The Danish study mentioned in the beginning showed that keeping the daily intake of bioflavonoids at 500 mg or more prevented 18% to 39% of heart attack mortality and 21% to 36% of cancer mortality.

In other studies we learnt that deaths between the ages of 80 and 100 were mainly due to heart attacks, strokes and cancer (these accounted for 58% of deaths). Only 1.1% of the men in that Swedish study made it to the age of 100.

More evidence that flavonoids and plant protein save lives

Another study measured the effect of green and black tea consumption: There was a 21% reduction of strokes with green or black tea consumption.

Another study found reduced cardiovascular mortality by 33%. Green tea reduced cancer mortality by 21%.

Another study showed that when plant protein replaced red meat there was an astounding drop of the all-cause mortality by 34%.

All of these studies show that you must eat enough flavonoids to protect yourself from heart attacks and cancer. Of course you also need to engage in a regular physical exercise program to stay fit and healthy.

How Can We Prolong Our Lives?

By Ray Schilling | Cardiovascular disease, cholesterol, diet, exercise, fish oil, Fitness, food, heart attack, Hormones, melatonin, mitochondria, Mortality, Nutrition, omega-3 fatty acids, Prevention, sleep, Stroke, sugar, telomeres, Vitamins and supplements

The question “How can we prolong our lives?” is something that fascinates many people. It is not one thing, one activity, one diet, or one lifestyle factor that determines longevity. It is the combination of all of the things listed below that are necessary.

Longevity is partially inherited from your mother

The reason for this is that mitochondria in your body cells come from your mother’s body. As you know, the egg (ovum) contains the mitochondria (the energy packages of the cell). The sperm that is the winner penetrating the ovum is shedding the tail outside the ovum. The tail of the sperm had loads of mitochondria in it to give it the energy to wiggle its way up the Fallopian tube to meet the ovum. This is the reason why we all inherit our mitochondria from our mother. If there is longevity on your mother’s side, you likely will have the longevity gene as well. So, this certainly helps, but on the other hand, we cannot pick our ancestors! Don’t be discouraged! There is enough that you can do.

Diet

The best type of diet is a Mediterranean-type diet. There is a new fasting mimicking diet, that likely turns on latent longevity genes that need to be intermittently activated, if we are serious about wanting to increase longevity. Dr. Longo is the inventor of the fasting mimicking diet. I have discussed this in detail here. Briefly, it consists of eating 500 to 600 calories on 5 consecutive days. The rest of the month you eat normally. The important part is that Dr. Longo has shown in humans that telomeres get elongated by the 5-day protocol per month. Longer telomeres means longer life. This is what we want, because this adds life to our life expectancy!

Lifestyle

Don’t smoke and don’t do drugs. Drugs interfere with our hormone- and other cell surface receptors. Our body cells don’t like artificial chemicals from outside. Don’t overlook the fact, that alcohol is also a drug! Alcohol is a nerve and cell poison. It has been shown to even be toxic, so don’t drink all the time. If you want a drink here and there, you probably get away with it. But binge drinkers (6 drinks or more in one evening) are out of luck; their life expectancy is shorter than that of non-drinkers.

Exercise

Regular exercise recharges your mitochondria to give you extra energy. It conditions your heart and lungs and also your muscles. Many people think exercise would cause weight loss. But it is not leading to that much weight loss at all! What is more important is the fact that it is reducing the overall mortality from many diseases by up to 47%! Exercise also improves blood sugar control, energy levels and sleep patterns. There are also hidden benefits, as the heart is being conditioned and the lungs are improving their vital capacity from regular exercise, particularly aerobic exercises like running or using a treadmill. But muscle strength also benefits from regular exercise.

Get enough sleep

You need 7 to 8 hours of sleep, and it is best to go to sleep between 10 or 11 pm. During your sleep your brain is being renewed and your hormones are reloaded. There is a diurnal hormone rhythm that ensures you have enough energy for the following day. A Swedish study found that longtime shift workers had a 28% higher mortality compared to a control group of daytime workers: Shift work and mortality.

Vitamins and supplements

Some minimum vitamin and mineral supplements are helpful for longevity: Mornings: 2 capsules of molecularly distilled fish oil (omega-3 fatty acids). Two tablets of vitamin C 500 mg chewable, one capsule of 150mg of chelated magnesium, resveratrol 500mg, vitamin B complex B-50, zinc 30mg, vitamin K2 two capsules of 100 micrograms, vitamin D3 5000IU every morning, CoQ-10 400mg. Evenings: 2 capsules of molecularly distilled fish oil (omega-3 fatty acids). Vitamin B complex B-50, chelated magnesium 150mg, melatonin 3mg to fall asleep, valerian root 500mg capsule (if you have anxious thoughts); you may repeat melatonin and valerian root in the middle of the night, if you wake up at 2AM or 3AM in the morning.

Brief explanation for vitamin and mineral replacement

In case you wonder about the rationale of my suggestion for vitamin and mineral replacement, here is a brief explanation: vitamin C stimulates the adrenal glands and helps support the immune system. You get more energy and get fewer infections. Molecularly distilled fish oil is anti-inflammatory, helps prevent osteoporosis, but also prevents heart attacks by preventing inflammation of the arteries. Magnesium and zinc are co-factors in hundreds of biochemical reactions inside our cells, so this helps your metabolism.

Resveratrol an anti-aging supplement

Resveratrol is a bioflavonoid derived from red grapes. It has multiple beneficial effects. It lowers blood pressure, helps to control diabetes better and prevents osteoporosis. But resveratrol also elongates telomeres, which translated into a longer life and less diseases. B complex vitamins are good for energy and many metabolic processes. Vitamin K2 and vitamin D3 work together to get calcium out of our arteries and deposit calcium into our bones. This prevents osteoporosis, which is particularly important for postmenopausal women, but is also important for men. Resveratrol also prevents heart attacks and strokes. CoQ-10 is important to lower cholesterol, but also supports the metabolism of mitochondria, the energy packages of our cells.

Hormone deficiencies

We all know that there is menopause for women and andropause for men. But there are silent hormone deficiencies that are less well known. For instance melatonin secretion gets reduced fairly quickly after the age of 20. Between the age of 50 and 60 you are basically deficient for melatonin, so using a supplement of melatonin tablets would be very reasonable. Another hormone, namely human growth hormone (HGH) is very likely deficient in us by the time we are 50 to 60 years old. I will deal with this further below.

Menopause

Women get into menopause between 45 and 55, but they can get there earlier or later. Women are missing estrogen and progesterone. Many women were horrified by the Women’s Health Initiative result in 2002. But this trial involved synthetic hormones that the body did not like. So women got breast cancer, colon cancer, heart attacks and strokes from Premarin and Provera, both synthetic hormones. Had physicians been sensible and put them on bioidentical hormones instead, they would have prevented heart attacks, strokes and osteoporosis. They would also have prevented breast cancer and colon cancer. The proper way to replace missing hormones in women with menopause is to replace them with bioidentical progesterone cream and bioidentical estrogen cream.

Andropause

Men get into andropause between 55 and 65. The testicles will no longer provide the man with enough testosterone. This leads to lack of sex drive, erectile dysfunction, but also to more heart attacks, muscle weakness and a lack of energy. The problem is that there is not enough testosterone to stimulate the mitochondria. Mitochondria are very prominent in the heart muscle, skeletal muscles, but also in the brain. When the doctor confirms a lack of testosterone with blood tests, he orders replacement with bioidentical testosterone cream or by a simple testosterone injection twice per week. The man will feel better after a short period of time (4 to 6 weeks) as all his functions return back to normal.

Many speakers at anti-aging conferences, which I attend every December in Las Vegas, seem to agree that bioidentical hormone replacement adds 10 to 15 years of life both in men and women. It also gives people renewed energy, and they look younger.

Human growth hormone

Many people do not know that human growth hormone (HGH) is important for longevity in adults. In childhood it was important for bone growth. Growth hormone deficiency is the one factor that has been underestimated. The discussion of dwarfs in comparison to their healthy brothers and sisters showed us the following. Growth hormone production can add between 19 and 34 years (average 26.5 years) of life. Dr. Hertoghe, an endocrinologist from Belgium has done blood tests (IGF-1) and lately also 24-hour urine metabolite tests of growth hormone on aging patients and found that many were deficient with regard to HGH production. These were patients where Dr. Hertoghe already replaced their thyroid hormones, if abnormal and replaced their sex hormones when they were low.

Symptoms of human growth hormone deficiency

But they lost hair, developed old looking faces with wrinkles. In addition, a loss of subcutaneous fatty tissue is giving the face a hollow appearance. They also had muscle and joint pains and thin skin, particularly over the back of their hands.

Replacement of growth hormone

He replaced their missing HGH using daily HGH self-injection with a tiny needle (similar to diabetes injections). Within 1.5 to 3 years the wrinkles disappeared, the faces started to look younger and patients did feel younger. Their muscle and joint pains had disappeared and their hair grew back. The dosage range is between 0.1mg and 0.3mg, a tiny amount of HGH daily. This is not inexpensive, but some health care plans pay for this, as a lack of HGH is a true hormone deficiency.

How Can We Prolong Our Lives?

Conclusion

I have given you an overview of the important elements of what increases longevity. The key is to have a healthy, balanced diet and leave junk food out. Don’t smoke and don’t drink excessive amounts of alcohol. No alcohol consumption would be best, because alcohol essentially is a nerve poison and can lead to dementia. Exercise regularly to lower mortality and strengthen your heart and lungs. Get enough rest and sleep to refresh your diurnal hormone rhythm. When we age, it is important to keep an eye on our hormones. You need a physician who is knowledgeable about it.

Hormone replacement

Hormones that are missing need to be replaced by bioidentical hormones. In addition you need to know what the level of IGF-1 is. HGH controls the IGF-1 level. If IGF-1 is low, you need HGH replacement. Studies have shown that replacement of missing HGH may be able to add 2 decades of good life. All of the other hormones replaced by bioidentical hormones will add 10 to 15 years. As stated in the beginning, there is not one thing only that increases longevity, but a combination of all these factors.

Fasting Mimicking Diet Is Very Relevant For Health And Longevity

By Ray Schilling | diet, Health, Nutrition, Prevention, stem cells, telomeres

Several speakers in Las Vegas said that the fasting mimicking diet is very relevant for health and longevity. This happened on day 1 of the 26^th Annual A4M World Congress 2018 in Las Vegas.

What were the findings that are relevant?

Dr. Longo has done a lot of animal experiments with intermittent fasting and studying longevity. He repeated what he has learnt over the years from animal experiments and from research on humans. Here are the results that he shared already at last year’s Anti-aging Conference in Las Vegas.

Effects of fasting mimicking diet

Obesity diminishes, because of the weight loss effect due to missing calories.
Diabetes: insulin resistance becomes lower and blood sugar levels drop.
High blood pressure reduced: many patients were able to reduce their medications or discontinue them
Pain conditions improve as all kinds of pain disappears, an effect for which there is no explanation at this point
Autoimmune diseases like MS and rheumatoid arthritis improve, likely because of the effect of increased stem cell circulation
Prevention of heart attacks and strokes because of reduction of LDL, triglycerides and CRP
Cancer cure rates improve by protecting normal cells and the bone marrow
Longevity improved in mice with a 3-fold increase of their life span. Telomere length in humans was increased. Increased stem cells will find defective areas that need repair. This effect leads to less disease in older age.

Increased life span, less heart attack and cancer rates

We know from these animal experiments that mice have a threefold increase in life span. But when heart attack rates and stroke rates improve in humans, cancer cure rates improve and telomere length in humans increase, there is strong evidence that it increases human life expectancy as well. It may take another 10 to 20 years before we have better statistics about the real survival advantage on this diet versus the Standard American diet. But what we know now is a significant start.

Patients on chemotherapy and FMD have much better healing rates than controls

The lecture by Dr. Longo on Dec. 13, 2018 did provide more human data. Patients undergoing chemotherapy tolerate and survive chemotherapy much better when combined with the fasting mimicking diet (FMD). The human data is very similar to the previous mouse model data. This human research was done at the Charité Hospital in Berlin, Germany. Dr. Longo is starting to engage in clinical trials by partnering with physicians, but the publication of this will take several years. In the meantime the FMD is an effective way to rejuvenate on an ongoing basis. Since last year I underwent 12 courses of 5-day FMD every month. Dr. Longo says that even 3 to 4 courses of FMD per year would have a lasting rejuvenating effect.

About the right food intake and getting enough sleep

Dr. La Valle gave a talk in the afternoon of the first conference day where he pointed out several important things. He started his talk by saying that North Americans eat the wrong foods, they eat too much of it and they often eat it at the wrong time (in the middle of the night when the body wants to rest). This can interfere with our diurnal hormone rhythm, which in turn will eventually lead to inflammation in the body. Fasting overnight rests our hormone receptors so they are fully active the following day.

Preventing Alzheimer’s disease

Dr. La Valle praised the FMD as being able to elevate brain derived neurotropic factor. Newer research is pointing at the importance of this factor for preventing Alzheimer’s disease and Parkinson’s disease. He pointed out that the FMD is a good start to change other things in a patient’s life. Such things like exercise, bioidentical hormone replacement and taking vitamins and supplements. All of these all in combination will build up a patient’s health.

More human data about anti-aging

The internist, Dr. Kurt Hong said that he is seeing 200 patients every week. He has done clinical studies on various forms of fasting. The FMD, he said he liked best as it is easy to do (5 days out of one month 500 calories on each of the FMD days). Dr. Hong has seen amazing improvements in patients with MS, Hashimoto’s disease and Crohn’s disease. His talk concentrated on how fasting improved the metabolic syndrome, improved inflammation in the body and improved immune diseases. The FOXO pathway involves transcription factors that are important to regulate cell death (apoptosis). A variant of FOXO3 is responsible for longevity in humans and has been found in centenarians.

Dr. Hong pointed out that self-cleaning (autophagy) is an important rejuvenation process in the body. The FMD stimulates this process. In a 2017 study Dr. Longo and Dr. Hong compared 100 regular patients with 100 patients on the FMD. Only the patients on the FMD showed that the body weight came down. In addition the blood pressure came down as well and the pluripotent stem cells in the blood were up. So, the FMD has a positive effect on various organ systems without any medication. The strongest effect of the FMD would be in the age group of 20 to 40 for anti-aging purposes as it stimulates stem cell production and elongates telomeres.

Fasting and women’s health

Dr. Felice Gersh gave a talk about the effects of fasting on women’s health. She pointed out how important estrogen is in a woman for every organ system. All of the major organ systems including the skin have estrogen receptors. Estrogen stimulates the metabolism. It stimulates the immune system by stimulating macrophages that also have estrogen receptors. In menopause less estrogen production leads to a lack of energy, because the mitochondria are no longer stimulated as they were before. Estrogen also stimulates sirtuins, which is important for anti-aging. Studies with the FMD have shown that estrogen production is re-stimulated in women.

Dr. Joel Kahn was another speaker in the afternoon. He talked about how important the FMD is for cardiovascular health. He does not think that coronary artery surgeries and stents will suddenly get abandoned, but he thinks that the FMD is a powerful tool to delay arteriosclerosis in the arteries. This will delay coronary artery lesions from developing and will add life. In his opinion 40 to 60 year old patients should start using the FMD to prevent cardiovascular disease.

Aging drives chronic disease

Sebastian Brandhorst, PhD pointed out that if we stay active and eat healthy, we will age well. The US is the only country on earth where the life expectancy goes down after there was an initial health gain in the past.

Yeast, worms, flies and mammals follow a nutrient-sensing pathway. That means when food is not around, starvation increases resistance to a variety of toxins. One important aspect of the FMD is the observation that it protects the body against the toxic effects from chemotherapy. FMD and chemotherapy combined almost completely blocked progression of breast cancer in mice. Further studies showed that cytotoxic T cells were responsible for stopping cancer growth. When antibodies against T cells were administered, the beneficial cytotoxic T cell effects against cancer were wiped out. In humans the same protective effect of the FMD was observed. The FMD combined with chemotherapy gave the best survival data in cancer patients.

Fasting Mimicking Diet Is Very Relevant For Health And Longevity

Conclusion

The fasting mimicking diet (FMD) was ranking very prominently among last year’s anti-aging conference in Las Vegas. Several speakers of this year’s anti-aging conference pointed to the health supporting effect of the FMD. It is now evident that the previous findings in animal research are also true in humans. Missing at this time are prolonged clinical trials that analyze the mechanisms of why the FMD works so well. In the meantime everybody can safely use FMD 5 days out of every month, which will rejuvenate your system by gradually prolonging pluripotent stem cell activation and telomere lengthening. It is just a matter of time when the missing links will be filled in.

Intermittent Fasting May Benefit Health

By Ray Schilling | Cancer, Cardiovascular disease, cholesterol, diet, food, heart attack, stem cells, telomeres, Weight loss

There is a lot of discussion about the fact that intermittent fasting may benefit health. But there are a confusing variety of intermittent fasting schedules. This makes it difficult to compare notes regarding the specific effect of an intermittent fasting diet. Generally speaking when there is some form of calorie restriction, our body goes into a survival mode of operating. These types of diets provide enough nutrients to not get into malnutrition, but at the same time they may stimulate sirtuins, particularly SIR2. This is thought to be associated with longevity.

Various forms of fasting

Eating after 5 PM

The Taylors in the CNN article eat the same amount of calories, but they only eat after 5PM. They claim to have more energy and be less vulnerable to infections. They also think that they feel younger than in the past.

Fasting every other day

This was an observation in the 1980’s to help rats live longer compared to rats that have food available every day. Recent experiments on mice showed similar results: calorie restriction in whatever form leads to prolonged life and health.

Human fasting mimicking diet

A 2017 study on 100 humans divided this group into half. One half ate any food as they wished. The other half consumed only 800 to 1100 calories for 5 days of each month as a fasting mimicking diet. The experimental group had lower fasting blood sugars; cholesterol, triglycerides and other heart disease markers went down. The IGF-1 markers for various cancers also went down. The experimental group lost abdominal fat, but preserved lean body mass. Valter Longo, who co-authored the clinical study said that a human trial on longevity would almost be impossible to design, and would cost “a hundred million dollars or more. But if you look at the data from our trial … it would be hard to see how they would not live longer.”

5:2 diet

Patients are allowed to eat what they want for 5 days of the week, but then they restrict their diet for 2 consecutive days. The control group had no restriction of calories. The 5:2 experimental group had better glucose control and loss of abdominal fat than the control group.

Fasting can help you live-longer

Experts on calorie-restricted diets tell us that there is a switch in metabolism from burning glucose as fuel to using ketones as fuel. Extended periods of exercise will also cause a switch to using ketones as fuel. Repeated cycling from fasting to eating may also benefit our brain function. Intermittent fasting will help us cope better with stress and disease. But Dr. Longo says that this is only one aspect. He found in his research that with intermittent calorie restriction there is a multi-system regeneration going on. For instance, damaged white blood cells are depleted, stem cells are activated, blood sugar control is improved and heart risk factors are being controlled. Dr. Longo mentioned that when tissues are healthy and functional, risk factors for disease decrease.

Mechanisms behind longevity

Dr. Longo explained in detail the complex aging pathways that involve three components, IGF-1, mTOR and PKA. When lifestyle choices stimulate these genetic markers, accelerated aging is the consequence. But with the inhibition of those markers longevity will happen. Here are some of the effects on the body of a fasting mimicking diet.

Obesity diminishes, because of the weight loss effect due to missing calories.
Diabetes: insulin resistance becomes lower and blood sugar levels drop.
High blood pressure reduced: many patients were able to reduce their medications or discontinue them
Pain conditions improve as all kinds of pain disappears, an effect for which there is no explanation at this point
Autoimmune diseases like MS and rheumatoid arthritis improve, likely because of the effect of increased stem cell circulation
Prevention of heart attacks and strokes because of reduction of LDL, triglycerides and CRP
Cancer cure rates improve by protecting normal cells and the bone marrow
Longevity improved in mice with a 3-fold increase of their life span. Telomere length in humans was increased. Increased stem cells will find defective areas that need repair. This effect will open up a new chapter in medicine.

Intermittent Fasting May Benefit Health

Conclusion

Calorie restriction is a powerful method to rejuvenate the body. Surprisingly 5 days out of one month of a calorie restricted fasting mimicking diet is all that is necessary to improve the body’s metabolism. Telomeres get increased, damaged white blood cells are removed and stem cells get stimulated. But weight loss, improvement of pain perception and cardiovascular risk reduction take place as well. In mice longevity was significantly prolonged, but this needs to still be shown in humans.

One can think of an intermittent fasting mimicking diet as a kind of internal cleansing. Following this it is easier to restart the metabolism with clean ingredients.

So far I have followed 11 courses of the fasting mimicking diet. But I don’t buy boxes of 300.00 USD every month. Instead I count calories myself, keep the diet balanced and buy the ingredients in the health food store. I agree that the fasting mimicking diet seems to be effective and it helps to keep my body mass index under control.
